java - 为什么cucumber在所有胶水代码文件中运行@Before

Question

我的 cucumber 测试有问题。它运行 @Before 方法所有胶水类别。

例如。该功能文件在 MainStepDef.class 中有一个粘合代码。

#language: en
@run
Feature: Testing a feature
  Test before method

  Background: 
    Given stuff is created

  Scenario: The test
    When i do stuff
    Then stuff will be done

MainStepDef:

public class MainStepDef {

    @Before
    public void setup() {
        System.out.println("This is OK!");
    }

    @Given("^stuff is created$")
    public void stuff_is_created() throws Throwable {
    }

    @When("^i do stuff$")
    public void i_do_stuff() throws Throwable {
    }

    @Then("^stuff will be done$")
    public void stuff_will_be_done() throws Throwable {
    }

}

我有一个额外的粘合文件，名为:OtherStep.class

public class OtherStepDef {

    @Before
    public void setup() {
        throw new RuntimeException("No! Bad code! BAD CODE!");
    }

    @Given("^some other stuff is also created$")
    public void some_other_stuff_is_also_created() throws Throwable {
    }
}

终于我有了运行类(class)。

@RunWith(Cucumber.class)
@CucumberOptions(strict = true, tags = {"@run", "~@ignore" }, 
        format = {"html:target/systemtest", "pretty" }, features = "classpath:features/",
        glue = {"com.sorkmos.stepdef" }, monochrome = true)
public class RunFeatures {

}

当我运行此命令时，我从 OtherStepDef 设置方法中收到运行时异常。

为什么会发生这种情况？它不应该只执行该功能所需的粘合吗？

这是 Cucumber 的预期行为:https://groups.google.com/forum/#!topic/cukes/7gILvMsE2Js

This is the intended behaviour of the @Before and @After hooks: they are not related to each step definition. Every hook is run on each scenario (unless it's filtered out by tags).
